  • The purpose of this study was to research for anti-oxidation and anti-wrinkle effects of Acar mono Sap (AM). To cosmetic effect of AM, safety effect (MTT assay), anti-wrinkle effect (elastase, MMP-1 inhibition assay) and anti-oxidant effect (DPPH assay) were measured. When water extract of AM was used for cell viability, it was over 100% at 6% (6 ml/100 ml in phosphate buffer) concentration. AM showed 45.7% elastase inhibition and 23.7% MMP-1 inhibition at 50% (50 ml/100 ml in phosphate buffer) concentration so that it had good anti-wrinkle characteristic. And AM showed 68.9% antioxidation capacity at 50% concentration by using a DPPH assay. Consequently, AM can be used as natural materials or additives for human skin owing to their beneficial biologic functions, including the anti-wrinkle effect, for cosmetic compositions.

  • The decreasing effect of wrinkle on the pressure sensitive adhesive hydrogel patches containing ulmi cortex extract and sorbitol as the drug for anti-wrinkle were investigated. In this study, hydrogels were prepared by the crosslinking reaction of acrylic polymers and aluminum ions produced by L(+)-tartaric acid hydrolysis of the dihydroxy aluminum aminoacetates. The inhibition concentration of ulmi cortex extract on the collagenase exhibited at 0.01%. Furthermore, the moisturizing effect of hydrogel patches formulated with sorbitol was higher than that without it. In vivo animal test in hairless mouse showed that the ulmi cortex-loaded hydrogel patches had about 31.2% of anti-wrinkle effect compared to blank (before attaching the patches). Human test showed that only 33% of subjects showed the decreasing of wrinkle during 8 weeks. In conclusion, the model pressure sensitive adhesive hydrogel patches in this study would be pharmaceutically applicable for the wrinkle treatment on the facial skin.

  • It has been known that adenine is a very important material in living cells. Because, adenine is a member of nucleotide base, so it takes part in DNA, RNA and ATP synthesis. There are many reports that adenine participated in ingredients, especially DNA, RNA, NADH and ATP, affect on the cell. As well adenosine, conjugated adenine to glycoside, was known to anti-wrinkle compound. But there is no report whether adenine shows a good effect on the skin, especially anti-wrinkle. So, in this study, we tested whether adenine affects cell proliferation, collagen synthesis, collagenase synthesis inhibition in human dermal fibroblasts. In addition, we performed clinical study with adenine cream. Cell proliferation effect was tested by MTT assay. Collagen and collagenase synthesis were measured by Immunoassay with ELISA kit. Clinical study was performed by IECK according to KFDA Functional Cosmetic method. The results of cell proliferation show that 10$^{-6}$ ~10$^{-8}$ % of adenine increases cell proliferation about 50 % compare with non-treated control. At 10$^{-7}$ ~10$^{-10}$ %, adenine increases type I collagen synthesis about 50%, decreases type I collagenase about 22% compare with non-treated control. The results of clinical study show that 0.05% adenine treated group reduces wrinkle significantly compare with placebo treated group. Therefore adenine may be a new anti-wrinkle candidate, through increases cell proliferation and collagen synthesis dramatically. And it decreases collagenase synthesis. So adenine could be used as a new anti-wrinkle agent.

  • This study was to investigate anti-skin wrinkle effect of aronia extracts by extraction processes. The 70% ethanol extract by ultrasonification process (UEE) showed highest DPPH scavenging activity of 90.4% in order water extract (WE), 70% ethanol extract (EE) was measured 84.2%, 84.3%. collagen production measured $245ng/m{\ell}$ from UEE. WE was measured $53.5ng/m{\ell}$ and EE was measured $224.4ng/m{\ell}$. MMP-1 production was observed lowest $22.5pg/m{\ell}$ at UEE. MMP-1 production of EE was $34.6pg/m{\ell}$ and WE was $102.3pg/m{\ell}$. These results were found the highest antioxidant and anti-wrinkle effect at UEE among three processes. It was also confirmed that anti-skin wrinkle activities of the aronia extract was strongly correlated with anti-oxidant activities due to high amounts of antocyanins in the extract.

  • Bone morphogenetic proteins (BMPs) have diverse and important roles in the proliferation and differentiation of adult stem cells in our tissues. Especially, BMPs are well known to be the main inducers of bone formation, by facilitating both proliferation and differentiation of bone stem cells. Interestingly, in skin stem cells, BMPs repress their proliferation but are indispensable for the proper differentiation into several lineages of skin cells. Here, we tested whether BMP antagonists have an effect on the prevention of wrinkle formation. For this study we used an in vivo wrinkle-induced mouse model. As a positive control, retinoic acid, one of the top anti-wrinkle effectors, showed a 44% improvement compared to the non-treated control. Surprisingly, bone morphogenetic protein receptor 1a extracellular domain (BMPR1a-ECD) exhibited an anti-wrinkle effect which was 6-fold greater than that of retinoic acid. Our results indicate that BMP antagonists will be good targets for skin or hair diseases.

  • Inner nutshell of Castanea crenata has been used as an anti-aging and anti-wrinkle agent from the ancient time in east Asia. In order to develop new anti-aging and anti-wrinkle, ethanolic extract of inner nutshell of Castanea crenata was prepared and various biological activities were evaluated. Cor-285 possessed potent tree radical scavenging activity in vitro compared to gallic acid. Cor-285 showed the preventive effect against UV-induced cytotoxicity of fibroblast at concentration of 25-250mg/ml. When Cor-285 was evaluated for its anti-allergic activity, it effectively inhibited histamine release from mast cells induced by compound 48/80. The inhibitory activity was stronger than that of glycyrrhizinate. Cor-285 also showed on vivo inhibition against delayed hypersensitivity as well as croton-oil induced ear edema in mice when topically applied. These results strongly suggest that Cor-285 may reduce immunoregulatory/inflammatory skin trouble. From the attempts to isolate the scavenger, were isolated. In a clinical trial of twenty healthy volunteers with aged skin, 6 weeks application of Cor-285 decreased wrinkle about 26% and increased moisturizing 20% on the skin. All of these results indicate that Cor-285 may be an effective anti-aging and anti-wrinkle agent.

  • 새로운 주름개선 효능물질을 개발하기 위하여 여러 가지 세포배양 모델을 이용한 in vitro 효능물질의 검색방법을 이용하여 후보물질을 도출하고 있다. 이처럼 In vitro에서 선별된 주름개선 후보물질은 사람피부에 직접 도포 하였을 때 in vitro에서 와 는 달리 주름개선 효능이 없는 경우가 많이 있다. 즉 in vitro 검색결과와 사람피부에서의 효능은 현실적으로 큰 차이를 보인다는 것이다. 그러나 모든 효능 후보물질을 사람 피부에 직접 검사할 수는 없는 현실적 어려움이 있다. 이러한 애로점을 해결하기 위하여, 동물모델이나, 인공피부배양모델 등을 이용하는 추세이다. 이번 강의에서, 본인은 동물모델과 in vitro에서 효능 측정방법을 상세하게 리뷰 하고 각 방법에 대해 토의할 것이며, 임상 전 시험 결과를 보고 할 것이다. 그 중 특히 동물 모델은 주름개선 효능물질의 효능을 평가하는데 좋은 대상이 될 것이다.

  • In this study, we evaluated the anti-oxidative, anti-wrinkle and whitening effect of Duchesnea indica (Andr.) Focke extract. Duchesnea indica (Andr.) Focke was extracted by two different solvents which were n-hexane and ethyl acetate. The anti-oxidant activity was measured by free radical scavenging activity using DPPH (1,1-diphenyl-2-picrylhydrazyl radical). And the inhibitory activities of tyrosinase for whitening effect and collagenase for anti-wrinkle were investigated. For anti-oxidant activity and whitening activity, ethyl acetate fraction of Duchesnea indica (Andr.) Focke extract showed more significant activity than n-hexane fraction of Duchesnea indica (Andr.) Focke extract. For anti-wrinkle activity, ethyl acetate fraction of Duchesnea indica (Andr.) Focke extract exhibited strong inhibition effects compared with reference. Therefore, Duchesnea indica (Andr.) Focke extract may be useful as a new antioxidant and anti-aging agent.

  • The bark of the root and stem of Ulmus davidiana var. japonica has been used as a traditional Korean medicine to treat inflammatory disorders. This plant reportedly shows antioxidant, anticancer, and anti-inflammatory effects. In this study, we investigated the protective effects of Ulmus davidiana var. japonica ethanolic extract (UDE) on UVB irradiation-induced wrinkle in hairless mice. We evaluated for their free radical-scavenging activities against 1,1-diphenyl-2-picrylhydrazyl (DPPH) and the anti-elastase activities, and for their anti-matrix metalloproteinase-1 (MMP-1) activity in human skin fibroblast cells. In the wrinkle measurement and image analysis of skin replicas, the results showed that UDE significantly inhibited wrinkle formation caused by chronic UVB irradiation. These results suggest that UDE has anti-wrinkle activity.
